Roof vents are an important part of how your roof functions. Their primary job is to remove hot air or moisture from your attic, but there are several different types of venting options. Roof vents that work well can help decrease the risk of mildew development and decrease heating and cooling bills. Let’s discuss the most common types of built-in roof vents.
1. Box vents
These vents, also known as flat vents or low-profile vents, have no moving parts and are installed over a hole that is cut out on the roof. They use natural convection, creating an opening for rising hot air and moisture to be released. They are generally seen in metal or hard plastic and are most efficient when installed close to the roof ridge.
2. Power vents
These are also known as power attic vents and can be installed on the roof. They have motors that use fans to get hot air and moisture out of the attic. Some power vents have thermostats that can be triggered to turn on at certain temperatures, so it can keep heat build-up out of the attic area. These vents use electricity to run, but there are also models with solar panels that are built into the unit.
3. Wind turbines
These vents have moving parts but no motors, relying instead on wind to power their movement. They are more effective than box vents because they will be able to move more air up and out of the attic — especially when it’s windy outside.
4. Ridge vents
These vents have no moving parts and can be installed along the full length of a roof’s horizontal ridge. When used with soffit vents, this roofing ventilation system is highly effective in reducing moisture and hot air build up.
5. Soffit vents
Soffit vents are most commonly used to provide a way for air to be drawn in through the roof ventilation system. They are installed on the eaves of homes and are generally made of wood, aluminum or PVC material. This venting system is most effective when used in tandem with a continuous ridge vent or the other venting options mentioned above.
